HIGHWAY GUARD.

Application filed December 13; 1927. Serial No. 239,805.

My invention relates to'the construction of a guard rail for highways and has for its object to provide a structure of this kind which is at once very simple, very strong,

very eflicient and of comparatively low cost. The nature of my invention will be best understood as described in connection with the drawings-in which it is illustrated-and in which 0 Figure 1 is a perspective view of a highsupported at different heights from the way guard embodying my improvements.

Figure 2 is a plan view of one of the posts of the guard with the parts immediately attached to it, showing a preferredfeature of construction not shown in the smaller scale drawing of Figure 1.

Figure 3 is a face View of the structiue shown in Fig. 2.

Figure 4 is a side elevation of the structure shown in Fig. 2.

7 Figure 5 is a View similar to Fig. 2, but showing still another preferred detail of construction, and

Figure 6 is a side elevation of the structure shown in Fig. 5.

A, A, A, are the supporting posts of the highway guard which may conveniently be, as illustrated, made of eye beams firmly an: chorcd in concrete foundations. B, B, etc., indicate bow springs, preferably of U shape, secured firmly to the tops of the posts and having free ends extending out from the posts in the direction of the highway. Where my preferred form of a U shaped spring is used, the springs are secured centrally to the post, as shown, with the free ends extending outwardly toward the high- Way. B B etc., indicate eyes formed on the ends of the springs for the support of the cables indicated at D. O, C, indicate clips for holding the springs to the posts. As shown in Figs. 2, 3, and 4, the eyes for supporting the cables are formed separately from the springs and detachably secured to the spring ends by bolts; these detachable ends are indicated at 13 As shown in Figs. 5 and 6, the ends of the springs indicated at B are bent at a right angle to the body of the springs and in this modification I have also indicated the detachable clips shown at b for holding the cable on the ends of the springs.

It will be seen that by-my construction the the posts but are admirably adapted to'give co the desired resilience to the guard. To take up blows of colliding vehicles it is prefera le to provide, as I have shown, two cables ground and the U shaped bow sprin s which 05 support these cables are again a mirably adapted to take up shocks.

I prefer to support the cables directly on detachable devices which can easily be replaced in case of injury. I

My preferred modification shown in Figs. 5 and 6 is one which avails itself not only of the elasticity of the bow spring against shocks in the direction of the supporting posts but also by means of the twisted ends indicated at ,'provides elasticity in the direct on in which the cables extend so that a vehicle coming in contact with these twisted ends will meet with resilient reslstance.

Having now described my invention, what I claim as new and desire to secure by Let ters Patent, is:

1. A highwag guard comprising a row of spaced posts ow springs secured to the 5 posts with their free ends extending outward from the posts towards the highway and a cable supported on the free ends of the bow springs. I

2. A highway guard comprising a row of spaced posts, U shaped bow springs centrally secured to the posts with their free ends extending outward towards the highway and two cables one supported on the upper and the other on the lower free spring 5 ends.

3. A highway guard having the features of claim 1, in Wl'llCh the cable is supported on the spring ends by means of a detachable supporting device.

4:. A highway guard having the features of claim 1, in which the ends of the springs are bent to a right angle with respect to the body of the spring.
